Isihloko okufanele sikwazise ngasoAmavalvu ebhola le-PVC
Umsebenzi we-valve yebhola ye-PVC
I-valve yebhola, ingxenye yokuvula nokuvala (ibhola) iqhutshwa yisiqu se-valve futhi ijikeleza i-axis yesiqu se-valve. Isetshenziswa kakhulu ukusika noma ukuxhuma i-medium epayipini. Iphinde isetshenziswe ekulawuleni uketshezi nokulawula. Phakathi kwazo, i-valve yebhola enomumo we-V eqinile inamandla okusika aqinile phakathi kwe-core enomumo we-V kanye nesihlalo se-valve yensimbi ye-carbide eqinisiwe. Amandla okusika afaneleka kakhulu kuma-media aqukethe imicu nezinhlayiya ezincane eziqinile.
Ivalvu yebhola enezindlela eziningi epayipini ayikwazi nje ukulawula ngokuguquguquka ukuhlangana, ukuphambukisa kanye nokushintsha kwendlela yokugeleza kwe-medium, kodwa futhi ingavala noma yimuphi umzila owodwa ukuze ixhume ezinye iziteshi ezimbili. Le valve ngokuvamile kufanele ifakwe ngokuvundlile epayipini.
Ukuhlukaniswa kwamavalvu ebhola: ivalvu yebhola yomoya, ivalvu yebhola kagesi, ivalvu yebhola ephathwayo.
Ulwazi Oluyisisekelo
Ukusetshenziswa kwevalvu yebhola le-pvc ngokuvamile akudluli ku-45 ℃, futhi le ndlela ayifaneleki izinyibilikisi eziphilayo kanye nama-oxidant aqinile. Ngokusho kwalesi simo, lolu hlobo lwevalvu yebhola lungasetshenziswa kuphela koketshezi olungaphansi kuka-45°C futhi ingcindezi ingaphansi kuka-1.0mpa.
Uma kuqhathaniswa namanye ama-valve, inezinzuzo ezilandelayo.
1. Ukumelana okuphansi koketshezi
I-valve yebhola inokumelana okuncane kakhulu koketshezi phakathi kwawo wonke ama-valve. Ngisho ne-valve yebhola enobubanzi obuncishisiwe inokumelana okuncane kakhulu koketshezi. I-valve yebhola ye-PVC iwumkhiqizo omusha we-valve yebhola owenziwe ngokwezidingo zoketshezi oluhlukahlukene olubolayo lwamapayipi. Izinzuzo zomkhiqizo: isisindo esincane, ukumelana nokugqwala okunamandla, ukubukeka okuncane nokuhle, isisindo somzimba esincane, ukufakwa okulula, ukumelana nokugqwala okunamandla, ububanzi bokusetshenziswa, izinto ezihlanzekile nezingenabo ubuthi, ezingagugi, ezilula ukuzihlukanisa, ukulungiswa okulula.
Ngaphezu kwezinto zepulasitiki ze-PVC, ama-valve ebhola epulasitiki afaka phakathi i-PPR, i-PVDF, i-PPH, i-CPVC, njll.
2. I-valve yebhola ye-PVCinokumelana okuhle kakhulu nokugqwala.
Indandatho yokuvala isebenzisa i-F4. Ukumelana okuhle kakhulu nokugqwala futhi kwandisa isikhathi sokuphila kwenkonzo. Ukujikeleza okuguquguqukayo futhi kulula ukuyisebenzisa.
3. Njengevalvu yebhola ebalulekile,I-valve yebhola ye-PVCinezindawo ezimbalwa zokuvuza, amandla aphezulu, futhi ivalvu yebhola yohlobo lokuxhuma kulula ukuyihlanganisa nokuyiqaqa.
Ukufakwa nokusetshenziswa kwevalvu yebhola: Uma ama-flange kuzo zombili izinhlangothi exhunywe nepayipi, amabhawodi kufanele aqiniswe ngokulinganayo ukuze kuvinjelwe ukuthi i-flange ingakhubazeki futhi ibangele ukuvuza. Phendula isibambo ngokwewashi ukuze sivale, futhi ngokuphambene nalokho ukuze sivuleke. Singasetshenziswa kuphela ekunqamuleni nasekugelezeni, futhi ukulungiswa kokugeleza akufaneleki. Uketshezi oluqukethe izinhlayiya eziqinile lungaklwebha kalula ubuso bebhola.
4. Imisebenzi enamandla:
Uhlobo oluhlakaniphile, uhlobo oluhambisanayo kanye nohlobo lokushintsha konke kuyatholakala, futhi ivolumu incane: ivolumu ilingana cishe nama-35% emikhiqizo efanayo.
5. Abantu abalula futhi abashibhile:
Isisindo singama-30% kuphela emikhiqizo efanayo, futhi ukusebenza kwayo kuthembekile: amabheringi kanye nezingxenye zikagesi kuyimikhiqizo ethengiswayo engenisiwe.
6. Muhle futhi unesandla esivulekile:
Igobolondo eliphonswa nge-aluminium alloy die-cast, elithambile nelibushelelezi, elinamandla aphezulu kanye nokumelana nokuguguleka: igiya elikhethekile le-copper alloy elenziwe nge-worm, elinamandla aphezulu kanye nokumelana okuhle nokuguguleka.
7. Isiqinisekiso sokuphepha:
I-voltage yokumelana ne-1500v, i-wire lock ekhethekile yekhebula lokukhiya ilula: ugesi wesigaba esisodwa, i-wire yangaphandle ilula kakhulu.
8. Kulula ukuyisebenzisa:
Ukuhlolwa kwezindawo okungenawoyela, ukungangenwa manzi futhi okuvikela ukugqwala, ukufakwa kunoma iyiphi i-engeli, idivayisi yokuvikela: umkhawulo ophindwe kabili, ukuvikelwa kokushisa ngokweqile, ukuvikelwa kokulayisha ngokweqile.
9. Isivinini esiningi:
Isikhathi sokuhamba sisonke singamasekhondi angu-5 kuya kwangu-60, okungahlangabezana nezidingo zezimo zokusebenza ezahlukene. Ucingo olukhethekile lwenziwe ngocingo olungashisi futhi oluvimbela ilangabi, olungagugi uma lushiswa, futhi luphephile futhi luthembekile.

Yimaphi amakhono okulungisa i-valve yebhola le-pvc
★ Uma ivalvu yebhola ivuza ngenxa yesibambo esikhululekile, cindezela isibambo nge-vise, bese uphendula isibambo ngendlela ephambene newashi ukuze usiqinise. Kufanele kuqashelwe ukuthi udinga ukuqaphela lapho uqinisa isibambo, ungasebenzisi amandla amaningi, ngaphandle kwalokho ivalvu yebhola izolimala kalula.
★ Uma ukuxhumana phakathi kwevalvu yebhola le-pvc nepayipi lamanzi kungaqinile, ukuvala kungakuhle, futhi kukhona ukuvuza kwamanzi, ungayisonga ivalvu yetheyiphu yezinto zokusetshenziswa endaweni lapho ipayipi lamanzi lixhuma khona ibhola, bese ufaka ivalvu yebhola ngemva kokuyigoqa ukuze ugweme ukuvuza kwamanzi.
★ Uma kukhona ukuvuza kwamanzi ngenxa yokuqhekeka noma ukukhubazeka kwevalvu yebhola, ivalvu yebhola endala kufanele ihlukaniswe futhi ifakwe kabusha.
Kufanele kuqashelwe ukuthi ivalvu yebhola le-pvc idinga ukusebenza kahle lapho ihlukaniswa futhi ihlanganiswa, futhi amaphuzu alandelayo kufanele enziwe kahle.
★ Ngemva kokuba ivalvu yebhola ivaliwe, yonke ingcindezi evalvu yebhola kumele ikhululwe ngaphambi kokuyihlukanisa, ngaphandle kwalokho ingozi ingase ivele. Abantu abaningi abakunaki lokhu. Hlakaza ngokushesha ngemva kokuba ivalvu ivaliwe. Kusekhona ingcindezi ethile lapho. Le ngxenye yengcindezi ayikhululwa, okuyinto engasizi ngalutho ekuphepheni komuntu siqu.
★ Ngemva kokuba ivalvu yebhola iqaqiwe futhi ilungisiwe, idinga ukufakwa ngendlela ephambene neqaqiwe futhi iqiniswe, kungenjalo izovuza.
Uma ufuna ivalvu yebhola le-pvc ihlale isikhathi eside, kufanele unciphise inani lamaswishi ngangokunokwenzeka. Uma kukhona ukuvuza kwamanzi, udinga ukuyilungisa ngesikhathi ngokwezeluleko ezintathu esihlokweni, bese ubuyela ekusetshenzisweni okuvamile ngokushesha okukhulu.
